Hi, this is Yolanda Vanveen and in this segment we're going to talk about how to prune boysenberries. Boysenberries are so delicious and they just ripen and get so lush, and they produce great berries in the late summer into the fall. And when you're growing them it's really good to prune them. And the best time to prune them is when they're not producing fruit, so right in the fall and you just cut a lot of the new growth out and then that way they'll grow lush for the next year. So the goal with berries is to get a lot of growth. And so when you're pruning them back you should let them come up and grow and then take two main starts, and put them up onto a wire or a fence in anyway. And then when you're trimming back the different growth you should cut them in an odd even kind of arrangements. So you leave one a little bit longer, one a little bit shorter, one longer, one shorter, one longer, one shorter. And you never want to trim out more than 1/3 at one time. And the little suckers on the bottom too, it always helps to cut those out because then more energy will come to the top and you'll get lots more fruit. A lot of berries are grown in a two tier system as well; you can do a one tier or a two tier it's up to you. If you want a lot of fruit or if it's more established you can always add another tier later as they grow taller. So when there's a two tier system you just let the main branch grow tall and then you thin it out by taking two main stems and tying them onto the wire or rope or anything that you want. And then any branches that come off the top you want to trim them down. And again you never want to trim more than 1/3 of the plant at one time. And you want to prune when they're not growing and not producing fruit. So the best time to prune is in the fall or in the middle of winter when they're not growing too much. And then that way the next year they'll grow very full and it'll force the plant to give you even more berries, and you'll have a more successful season the next year. And the rule of thumb is to never prune them more than 1/3 and you'll find they'll grow really well.
